TI-RASPModel rocket altitude simulation program based on RASP-79E by G. Harry Stine, from his classic book "The Handbook of Model Rocketry". TI-RASP adapts RASP-79E to the TI-83+ and uses a list variable (ENGIN) to store thrust curve data for A8, B6, C6 and D12 engines. User-defined engines can also be added. This is a great teaching tool for high school students, as it shows practical applications of math and physics and supports hands-on experimentation.

Ballistic Trajectory Calculator Beta1This program will accurately calculate the trajectory of an object launched at a given angle and velocity. I apologize for how poorly this program is done, I do not have a calculator at the moment and programming is difficult.

Inverse Sum CalculationWhen calculating parallel resistors, series capacitors, or series springs, the resistance/capacitance/spring constant are added using the inverse sum rule. The sum is the inverse of the sum of the inverse of each component. Use this program to calculate the inverse sum.

Determining Coefficient of RestitutionThe coefficient of restitution, e, is important in analyzing collisions in physics. It's defined as (v1'-v2')/(v2-v1). A common way to determine this value is to drop a material (ball) from a certain height, and measure the rebound height. This program inputs those 2 values and gives the value for e.

Collision Velocity CalculatorWhen two objects collide, the collision may be elastic, inelastic, or completely inelastic. Enter the masses, initial velocities of the objects, and the coefficient of restitution, and determine the final velocities of both objects.

Physics 9000Tired of spending all your physics classes memorizing and rearranging formulas? Do you have a good understanding of the concepts but find the math a real pain? Now you can forget the math and get some real work done with Phys9000. It includes a vast library of physics equations that can be solved for any variable, with conversion to scientific notation. Phys9000 easily covers most, if not all of the average highschool physics curriculem, and has been thoroughly tested by students. It's user friendly and organized into a simple menu system. Phys9000 even includes sections for trigonometry, chemistry, unit conversions and a generic equation solver. Phys9000 also has modular source code, so it can easily be expanded by those so inclined. You don't even have to know much about TI-Basic as long as you follow the easy template shown in the readme. Anyway, I hope people get a lot of use out of Phys9000, I spent all semester writing and testing it. *This version fixes a nasty bug involving custom heat capacities for dual body energy transfer problems.

Physics HelpThis is a physics program I made for my high school freshman year physics class. It covers various topics 1dim motion, 2dim motion, vector addition, friction, momentum, energy, periodic motion, circular motion, including some AP ones such as friction on banked turns. You choose a topic, then choose a variable for which to solve, choose a set of givens, input the givens, and you get the answer. It has many different equations and sets of givens. I spent the entire year deriving the equations and working out things. I uploaded a group file. I recommend you archive everything, then ungroup the Physics1 and Physics2 groups. Then archive back whatever you think you don't need immediately. I think it's a great program, so try it out! This is a newer version from November 15, 2007.

The program works only with the following simple two-dimensional motion equations: d=vt+1/2at^2 V^2=v^2+2ad V=v+at where each variable has the following assignments: d = distance v (lowercase) = initial velocity V (uppercase) = final velocity a = acceleration t = time These equations can also be applied to rotational motion as the equations used in that field are identical, except for different variables; therefore, the program serves a dual purpose.
